ABSTRACT:
A ball pickup hopper on supporting wheels has a bottom panel contoured with channels extending from a front of the hopper to the supporting wheels. Extending forward of the hopper are opposing left and a right herding rails directing balls in front of the apparatus into the channels as the apparatus is moved over a ground surface. The supporting wheels are positioned and adapted for receiving balls moving through the channels, compressively rotating and lifting the balls between the supporting wheels and the hopper, and expelling the balls into the hopper through openings. A top cover is fitted to enclose the hopper and to alternately act as a base for supporting the hopper at an appropriate height for use in ball practice.
